Yep, 17 to 21 days per the Merck Veterinary Manual.

Your vet may have found coccidia in the stool sample, but that doesn't mean it was the cause of disease. Calf could have recently ingested, but not causing a problem.
Which reminds me when my boy was about 3 years old he had some vague bowel pains. We took him to world-class specialists in Utah for various tests and biopsies. One sample showed the parasite, giardia, a similar bug to coccidia. So we treated him for weeks with a high powered drug that turned him yellow. Still no improvement, so I flew him to an Army doc in Colorado who immediately diagnosed his problem correctly - he didn't want to poop so was holding it in until he got backed up! A few enemas, and he decided pooping was better.
The moral of the story is the presence of a bug does not mean its the cause of disease.
Are you sure the calves had a good dose of colostrum the first few hours after birth? Without that, an assortment of bugs will get them due to lack of immunity.
